I can answer some of those questions. The 12 switches can't be connected to the IPAC and on to MAME because the whole reason for converting down to only 2, is that MAME is only designed to look for the 2, so if someone wired up all 12 joystick rotation switches to a keyboard encoder, they would have no way to make use of them in MAME still. The basic difference is the joysticks tell you exactly where you are locked in during the rotation, but MAME is only looking to see which direction you're heading to when you start rotating, it doesn't need the 12 point accuracy that the joystick can provide. So the interface just looks at the 12 switches and when you start rotating, it will send the signals that MAME does want to see, thus why there's only the 2 instead of 12 for each player. So Dr D has just 2 ipac inputs used for player 1 and 2 more inputs for player 2's rotations.
I don't know of any 4 player rotation games, just 2 player... I think whenever I make a cabinet, I might still want to try out the optical joysticks, whether I go with one rotary and one optical, or have the opticals on a separate panel..I kind of want at least one of everything!
